To (ZZZ whom it may concern:

Be it known that I, AneUs'r IVIUELLER, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in IIatband-Looms, of which the following isa specification.

This invention is in the nature of improvements in looms. for making'hat bands.

Long experience in the manufacture of hat bands has revealed deficiencies in such looms and the present invention is intended to correct such deficiencies. The most important part of such looms is the so called quick change motion forelevating the shafts, and the present invention is an improvement thereon.

It is the general requirement in the art to manufacture mens. hat bands of the least material and of good quality, in contradistinction to the manufacture of ribbons. The silk warp used is selected of avery low twist and the warp to weave with little weight."

This circumstance involves the danger of manufacturing goods of a very bad quality, and in order to avoid this, the idea of the quick change motion has been developed.

' This part appears to' be the most important one in the looms used and needs adecided improvement, the present system belng a rigid unchangeable one. According to my improvements the system is made adjustable in every direction. 7

In order that the construction and operation thereof may be readily understood, I

have illustrated an improved embodiment of the invention in the accompanying draw 7 ing, and will now proceed to fully describe the same in connection with said drawing, in which Figure 1 represents a view of parts of the loom in side elevation, other parts being broken away;

Specification of Letters Patent, Patented Aug. 31, 1920.

Referring specifically to the drawings, from which are omitted most of the parts not im proved by this invention, instead of the larger pulley generally used in such looms I have made a two-armed lever 6 engaging the square rod 7, which lever has several advantages over the pulley. First, no leather straps, which frequently break, are necessary. The lever 6 is connected with the shaft wires by strong wires 8, and simultaneously the two arms are used as hammers, being provided with sliding weights 9, and by hanging the strong wires into different holes,fI obtain a higher or lower stroke of the shafts. The smaller pulley usually used I have replaced by two strong screw bolts 11 set into the rod, which I can screw out of or into the rod as I think advisable and these bolts are also in direct connection with the treadles 12 bywires '13, without the intermediary of leather straps. Thusthe loom will work toward all directions as may ing the screw bolts 11 toward the inside, and a I produce a very quick motion of the shafts.

Any one of the treadles may be adjusted or displaced. A new treadle guide 15 in which 1' v V movable springs work on loose iron bolts 16.,

When the treadle goes up the bolt 16 also goes up and compresses the spring, which naturally expands again and carries the treadle and shaft back into the correct position. This guide is very important for the good working of the loom for the manufacture of hat hands which are well covered, and show a good luster. v V p The wires. 8 pass over ,pul'leysf18 and down, being connected to the harness 19,70 any well known'construction, so that the harness will be operated bythe movement of the'two armed lever as the is reciprocally rotated. V

By means of the constructions described, I fully carry out the described objects of the invention, and I desire it to be underact mechanisms described, but may: make changes and variations therein, without departing from the spirit and scope of the in square rod 7 ica . stood that I do not confine myself tothe ex- V 3 Having thus fully described my invention,

What I claim as neW'and desire to secure by Letters Patent of the United States is 1. The combination With a shaft, of adjustable arms thereon, tre'adles, andrconnecting treadles comprising loosely 'mounted'verti cal slidable bolts and springs coiled around the bolts, said bolts beingmounted in an anengaging under thebolts. V v

2. The combination with a shaft, of a I double-ended arm centrally mounted thereon and having a series of holes in each end,

hammers 'adjustably mounted on the arm near each end, a loom harnessfand Wires connected from said holes and passing over pulleys to the harness. 7 V

In testimony whereof I aflix my signature. AUGUST MU Ii R;
